Too much weight
Recent posts concerning cracks around mast because of load pushing up on compression post had me worried, so I put rubber shims between the brackets and the boards. I noticed my H240 centerboard support bunk is bowed down and cracked. Probably still too much weight but these crappy Magic Tilt trailers have no means to make an adjustment. All of the supports are drilled at a preset (and wrong) location. Who made your trailer?
